0Many times people ask this question: have you seen god/ghost? Or do you believe in them? And you must have seen many people answering this as: I have not seen any of them. So how can I believe it? Well, this is not a philosophical question or any such sort of thing. The answer lies in Physics.
We all calculated de-Broglie wavelength in class 11 chemistry or class 12 physics. Now you have seen that the de Broglie wavelength for a macroscopic object is decidedly very less. Why is it so? The simple reason is that the value of Planck's constant h is of the order of 10^{-34} J.s, hence as a macroscopic object, we are unable to experience the wave nature of us. For an electron, de Broglie wavelength becomes significant as its mass is of the same order as Planck's constant.
Now, what happens, if the value of h becomes 1?or 10? or 100? Then we can experience our wave nature or someone else's wave nature. And maybe you will be able to experience both ghost and god, as they are the wave nature of a matter. So next time someone asks this question, explain them with this logic.
